Description
When you’re hearing that telltale knocking from down in the engine or feeling vibration through the cab, it’s usually your main bearings telling you they need attention. These bearings take tremendous loads, supporting the crankshaft while handling the constant rotation and power pulses that come with engine operation. This complete main bearing set gets your International Harvester engine back to smooth, reliable operation.
What You’re Getting
- Standard size bearings manufactured to handle the demanding conditions of agricultural use
- Direct replacement that fits without modifications or adapters
- Complete set with thrust flanges to control crankshaft end play
- Modern bearing technology with improved construction to outlast original equipment
Built for Real Farm Work
This bearing set fits International Harvester 100 series, 200 series, Super A-1, Super AV-1, and Super C tractors – the workhorses that have been earning their keep on farms for decades. These are the tractors that handle everything from loader work and cultivation to mowing and general farm duties where reliability matters most.
Made to Last
This replacement uses quality materials and precision manufacturing designed for reliability in agricultural applications, with construction that resists the stress and impacts that cause premature failure in demanding farm conditions. The bearings are properly heat-treated to handle the continuous loads and temperature cycles your engine sees.
Good to Know
Before installing new bearings, inspect the crankshaft for wear or damage since a damaged crank will destroy new bearings quickly. Clean everything thoroughly since old oil mixed with dirt acts like grinding paste, and use quality engine oil for proper lubrication. This is a job best left to an experienced mechanic with the proper tools for checking clearances.
